Two-thirds of cheaters are brazen enough to watch on their main TVs, and 21 percent watch in bed while their partner is asleep next to them.

NYM author Maureen O’Connor calls it “the smallest, most insidious betrayal” — the idea that you skip ahead on 30 Rock while your girlfriend is at work or watch an episode of House of Cards after your husband goes to bed.

In fact, a Harris Interactive poll put on by Netflix found that 51 percent of those in a relationship consider cheating, and 12 percent of Americans already have.

Amazingly, two-thirds of cheaters are brazen enough to watch on their main TVs, and 21 percent watch in bed while their partner is asleep next to them. Creepy.

For some reason, 5 percent cheat while in the bathroom — though if you’re spending 20-plus minutes on the commode, your partner probably isn’t going to ask too many questions when you come out.

Among young couples, 77 percent of men said they would cheat, while 57 percent of women admitted they thought about it. The lesson here? Trust nobody.

In fact, most people tend to hide the fact they cheated by not spoiling scenes (41 percent) or rewatching and pretending they were genuinely surprised by what happened on screen (12 percent).

Only 14 percent said they would feel guilty enough to confess. You’re all sociopaths.
